Hey guys,

I rigged up my own BHAF type setup with one of Amsoil's new Ea filters. It is a big 9" long, 4 inch inlet thing. I took the lid off the stock box, took IAT sensor off, and plumbed a piece of 60 degree bend PVC into the stock tubing from where it disconnected to the lid. I plumbed my restriction guage and IAT sensor into the PVC, attached filter to the other end of PVC, and the filter nestled nicely down right next to the cool air plumbing and uses the stock box for some shielding against engine heat.

Only problem was that I had my intake all apart and took my other truck to hardware store to get PVC, but the closest thing they had that would work was a 3.5" elbow that flared to 4" on the ends. So now I have a bottleneck in the system. And of course this is where I had to put the restriction guage. So I took it for a spin and loved the turbo whistle, etc. I checked everything out afterwards and the restriction guage was completely sucked down as far as it could go. My guess is that it is due to the higher velocity of going down thru that 3.5" section of PVC before it gets back to the 4" stuff. At least I hope so, I thought this filter would flow better than the Napa Gold I had in before.

Any thoughts? I will find a piece of full 4" PVC when I get a chance to get to a bigger store this week. Even on a light throttle run to the corner and back it sucked it down almost halfway.

BTW, I really like the build quality, looks, and feel of the Ea Cone Filters. Very nicely done.

 

i have the standard EaA189 drop in and no problems... take your shop air and blow across the minder and see if the high velocity air pulls it down...

 

Id have to bet that its the 3.5" section that is causing this and NOT the filter. These Cummins need a lot of air at full song, and thats an aweful small straw its trying to breath through.

 

Ignore the filter minder.

If you have a real compromise in airflow, you'll see it in EGTs.

 

I ran my truck at the strip with no filter and the guage bottomed out. They are useless on a modded truck.

 

Well for one thing I have no guages, and for another I have no performance mods other than exhaust, and now this intake setup. I was way too hard on my PSD with mods and it ended up costing me tons of money, and that memory is still pretty fresh in my mind--once you have all that power, it is very hard not to use it. And when you use it, chances are something is going to break eventually!

I know the filter is not causing this--I know on Fords a lot of times when they change the intake it messes with the parameters the filter minder was meant to work in, but it still doesn't give you a warm fuzzy feeling seeing it sucked down all the way. It might be my imagination but the turbo seemed slower to spool than it did before this.

I guess I will try and find a piece of PVC that is 4" all the way through, or even find a 4.5 or 5.0 that reduces to 4.0 on the ends. If it still sucks the minder down, heck with it, because I will know for sure at the point that it will be getting more air than stock regardless of what the idiot guage says.
